Each direction X, Y, Z is orthogonal to each other.

  An automobile equipped with an automatic driving system is configured to be switchable between manned driving for driving a vehicle based on a driver's operation and automatic driving for controlling driving of the vehicle based on information from various sensors.

First, based on FIG. 1, the handrest of 1st Embodiment is demonstrated.
The automobile includes a steering handle 2 for steering the vehicle. The automobile includes a rotating shaft 21 extending in the front-rear direction Y. The steering handle 2 is provided on the rotating shaft 21 and rotates around the rotating shaft 21 together with the rotating shaft 21. The automobile includes a control unit 23, a drive unit 24, and steering wheels 25. The automobile further includes a monitoring sensor 26 for monitoring a guide line on the road and a preceding vehicle. The drive unit 24 drives the steered wheels 25 based on a control signal from the control unit 23.

  In the manned operation, the rotation angle signal of the steering handle 2 (rotating shaft 21) is transmitted to the control unit 23, and the control unit 23 transmits a drive signal to the drive unit 24 based on the signal to drive the vehicle. The unit 24 drives the steered wheels 25 based on the drive signal.

  In the unmanned operation, the detection signal of the monitoring sensor 26 is transmitted to the control unit 23, the control unit 23 transmits a drive signal to the drive unit 24 based on the signal, and the drive unit 24 converts the drive signal into the drive signal. Based on this, the steering wheel 25 is driven. Therefore, during automatic driving, the steering handle 2 automatically rotates based on the driving of the steering wheel 25 of the vehicle regardless of the driver's intention.

  The automobile includes a handrest 1. The handrest 1 includes a pair of grip portions 10 and 10 for the driver to add hands. The grips 10 and 10 are disposed on the left and right outer sides (FIG. 1A) of the steering handle 2 and on the front side (FIG. 1B) of the steering handle 2. Furthermore, the grip part 10 is arrange | positioned in parallel with the steering handle 2 (FIG.1 (b)).

  The automobile includes a support portion 11 that supports both grip portions 10. The support part 11 is extended in the left-right direction X, and each grip part 10 is provided in each of the both ends. The automobile also includes a fixed shaft 22 provided on the same axis as the rotation shaft 21. The fixed shaft 22 is fitted into the rotating shaft 21 with a gap, and is fixed so as not to rotate even if the rotating shaft 21 rotates.

  The support portion 11 includes a through hole 11 a that penetrates the fixed shaft 22. The support portion 11 is fitted so as to be rotatable around the fixed shaft 22 through the through hole 11a. Further, the restricting portion 12 is fitted and fixed to the fixed shaft 22. The restricting portion 12 is connected to the support portion 11 and restricts the support portion 11 so that it can rotate only within a predetermined distance. Preferably, the restricting portion 12 has an electromagnetic or mechanical brake (not shown) for adjusting the resistance against rotation of the support portion 11 therein.

Therefore, the support portion 11 is provided to be rotatable around the fixed shaft 22 within a predetermined distance independently of the rotation of the steering handle 2 and the rotation shaft 21. In the present embodiment, the predetermined distance is 5 to 15 cm, and preferably about 10 cm.
Further, the steering handle 2 has a circular shape. Each grip portion 10 has an arc shape substantially parallel to the steering handle 2. And each grip part 10 becomes a diameter which is easy to grasp with a driver | operator's hand, for example, is 3-10 cm.
